British Gypsum Thistle BondingCoat – 25 kg
Thistle BondingCoat is a fine, pre-mixed gypsum undercoat plaster for smooth or low-suction surfaces such as dense blockwork, existing plasterboards, painted/tiled walls, and concrete. It provides an ideal base layer for subsequent finishing plasters, combining easy workability with reliable performance.
Features
- Fine, lightweight mix improves spreadability and ensures a smooth, consistent base coat.
- Predictable set (approx. 2 hrs) allows for planned workflow and finishing options.
- Single‐coat application (11 mm) eliminates layering and simplifies installation.
- Clear plastic 25 kg bag resists moisture and protects plaster integrity on-site.
- Environmentally aware formulation, with indoor air quality certification and EPD available.
Applications
- Undercoat on low‐suction surfaces: such as dense blockwork, engineering brick, concrete, plasterboard, and expanded metal lath.
